To all whom it may concern:

Be it known that I, NnrsoN E. FUNK, a citizen of the United States of America, residing at Montclair, countyv of Essex, State of New Jersey, have invented certain new and useful Improvements in Die- Pres ses, of which the following is a specification.

This invention relates to die presses and particularly to die presses provided with means for automatically feeding metallic de osit material to the die and for automatica ly detaching the used deposit material from the die.

The metallic deposit material may be in the form of a strip of paper bearing on one face the deposit metal adhering thereto by means of a fusible adhesive; the preferred form of deposit material is metallic powder agglutinated as a mass by means of a fusible agglutinant and adhering to a strip of paper, or equivalent, by means of such fusile agglutinant.

In the. preferred forms of the invention, means are provided for mounting a roll of the strip of paper bearing the metallic deposit, means for feeding such strip to the die and in proper relation to the book, sheet or the like to be ornamented or 'embellished. and means for detaching the used ortion of the strip after the impression has I en effected. In the more preferred forms of the invention, means are also provided for positively controlling and varying the g ctent of feed of the strip relative t the The particular form of the invention set forth in detail. hereinafter, is referred to in connection with a hot stamping or tip printing press, for use with deposit material ,applied by means of a fusible adhesive; however, as will appear, the invention is also applicable to other forms of printing presses or machines and to. other forms of deposit material.

Further featfires and objects .of the"'invention are more fully set forth in "the following description and the accompanying drawings. inwhich Figure 1 shows in side elevation ahand operated tip printing press provided with one form of my invention:

Fig. 2 is a front elevation of the same; Fig. 3 is a top plan view of the rear portion of Fig. 1, on an enlarged scale;

of the press at the stage of making the impression; and

Fig. 7 is a similar diagrammatic side elevation, but showing the deposit material strip in its fully detached position relative to the die.

Referring to the drawings, the particw lar type of printing press shown is a hand operated tip printing press, comprising the bed 1,.supported by the feet 2,'having the frame 3 for the die holder 4, operated by the hand lever 5 controlling the pressure link 6. The platen 7 is slidably mounted on the bed 1 and is provided with the burner 8, for pie-heating the die when held in the die holder 4. The die holder 4 may be guided by means of the slide rods 9, 9 and is normally biased toward its upper positlion by means of the expansion springs The roll 15 of paper strip bearing the metallized mass or equivalent deposit ma terial is mounted within the spool 16, rotatably mounted on the shaft 17 journaled in theopposite bearing brackets 18. I Such brackets 18, 18 are held together by means of the tie rods19 and suitably carried by the frame 3 or other fixed support.

The brake or friction means 20 is provided comprising the finger 21 adapted toresiliently ride on the back fa cc of the strip of paper and thus frictionallv preclude undue unwinding of the roll 15 said finger 21 is tensioned by the retractile' spring 22 having its one end connected to the. arnr mounted on the stud 25, journaled holder 4 and the'portion 29 of thepaper strip held adjacent, and more or less par.- allel, to the impression face of the die 30. Toward the rear end of the platen 7 is provided means for taking up the used portion of the paper strip; and in the particular embodiment shown in the drawings, I have indicated the upper idler 31 and lower idler 32 mounted in the pair of brackets 33, 33, suitably carried by the platen 7. Preferably, the used portion of the paper strip is wound on the take up roller 34, suitably carried by the bed 1 or other fixed support.

A portion 29 of the metallic strip is pro tected from the heat and flame of the burner is shown (see Fig. 3) supported from the platen 7 by means of the bracket 36.

For insuring theabsence of slack of the unwound portion 29 of the paper strlp, I employ the pressure roller 37, journaled with the take-up roller 34, in the opposite brackets 38, 39, supported on the bed 1, said pressure roller 37 being tensioned toward the take-up roller 34 by means of the oppositely disposed springs'40, 40, and rotated gearing 41, 42.

Accordingly, upon the paper strip being mounted and the unwound portion arranged as aforesaid, the operator positions the book 45, or sheet, or the like on the platen 7, and upon'movin the platen 7 to its operative osition as lndicated in Figs. 1 and 6, the ever 5 is depressed, causing the die holder 4 and the die 30, inserted therein, to be forced downwardly, whereupon a portion 46 of the paper strip 29 of the length of the effective face portion of the die 30 will be brought in operative relation to the die 30 and the article 45. After the impression has been made, the platen 7 is moved to its forward position on the bed 1 during which 6 to the stage ofentire removal of the paper strip from the. die 30,. the portion of the paper strip disposed between the roller 34 and the forward idle rollers 27, 28, is not fed in the direction of'its length, but moved downwardly to fully strip the used portion of the paper strip from the die and to dis-, pose the paper strip in a position out of possible damage from the heating means.

In order to more effectually utilize the advantages of the invention, I have provided means for automatically operating the take-up roller 34 a determined distance for.

jointly with the take-up-roller 34 by the taking .up the used portion of the paper strip, thereby automatically controlling the feeding of the paper strip and thereby fully utilizing the metallic deposit on the paper strip. I ;-f-

To attain such object, I 'have provided the rack 50 (see Figs. 1, 3 and 4) fixed to and rearwardly of the platen'7,the teeth of which rack .50 mesh with the teeth of the gear 51 (see Figs. 3, 4 and '5) controlling in ratchet relation the take-up roller 34, such ratchet means comprising the multiple rollers 52, v52, 52, respectively disposed in the triangular recesses 53, whereuponmovem'ent of the rack 50 in the direction of the arrow 54, see Fig. 4, causes the gear-51 to be rotated, and forces the respective ratchet, rollers 52 toward the constricted portion of the recesses 53, thereby rotating the take-up roller 34 and causing the paper strip to be definitely fed in relation to the die 30. Means. are provided for positively efiecting contact between the teeth of the rack 50 and the teeth of the gear 51 as by means of the pressure roller 55' mounted on the link 56 and resiliently forced downwardly by means of the spring-57. 1 i

Means are further provided forpositively controlling the extent of feed of the paper strip, such as the graduated element 60 bears ingthe linearscale markings 61 and shown as an extension of the body portion of the rack 50 and provided with thefixed rear- .ward stop 62 and the adjustable forward stop 63. The platen 7 is provided with the sleeve 64 fixed thereto and loosely extend-' ing about the'element 60.- The rearwardstop 65 is positioned on the bed 1 so that when the platen 7 encounters the same, the article 45 is in operative position for receiving the impression. Upon adjustment of the variable stop 63 as desired from zero -(extrerne right hand scale marking) the,

effective stroke of the element 60, or rack 50, and thereby. the extent ofrotation of the take-up roller 34 are positively controlled- Whereas I have described my invention by referenceto specific forms thereof, and in relation to a particular type of printing machine, it will be understood that many changes and modifications may be made without departing from the i-nvention as (IQ-\- tachin'g means comprising a plurality of device comprising two relatively movable elements and means for effectlng relative movement of the same, of means for mounting depositmaterial, means for feeding a portion of the deposit material to said ele-' ments in advance of the movement of said movement effecting means and means for detaching the used portion of the deposit material from said elements subsequent to the operationpf said movement effecting means,
